Specification of Letters Patent.

Patented J 1111a 16, 1914::

To all whom it may concern Be it known that I, Loam WV. BARGER, citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented new and useful Improvements in Ball-Joints, of which the following is a full, clear, and exact descriptlon.

My invention relates to ball oint connec: tions for pipes, and the particular ob ectof the same is to provide such a-connection w th two separate passages therethrough, wh ch are continuous through one part of the oint to the other part thereof, and permit the simultaneous passage therethrough of two separate bodies of liquids, gases or vapors in the same or in opposite directions. This I accomplish by the means hereinafter fully described and as particularly pointed out in the claim.

In the drawings: Figure 1 is a vertical transverse section of my invention. Fig. 2 is a cross-section therethrough taken on dotted line 22, Fig. 1. Fig. 8 is a vertical section through a slightly modified form of my invention. Fig. 4 is a plan view of the male member of the same.

Referring to the drawings, A represents the upper or female member of a ball joint connection for pipes. The lower part or socket a of this member is substantially semispherical, and this socket has a pipe-stub 1) extending vertically therefrom whose axis intersects the center from which the curvature of the concaved portion of said socket is struck. Near where the stub b merges into the socket a, this female member is provided with a lateral stub 0, which, preferably, projects at right angles to stub 79. The end of the bore or stub 6 opening into the concave side of said socket a is intended to be of such lateral dimensions as to substantially correspond in area to a cross-section of the upper portion of said stub. The orifice or opening cl connecting the bore of stub c with the concave side of the socket is below the lower end of the bore of stub b, and is, preferably, elongated horizontally, and this orifice ct may be of such dimensions as to correspond in area to the transverse dimensions of the bore of said stub, if desired.

Socket a of the female member A is adapted to receive the upper spheroidal end or head 2 of the lower or male member of my improved joint. This head is greater in diameter than the tubular portion 3 of the male member immediately below it, and the lower portion of the latter is reduced in diameter so that it substantially corresponds to the diameter of the stub b of the female member.

The head 2 and the portion 3 of the male member is divided by a longitudinally disposed web or partition 5 into two longitudinal passages, and the lower portion of this web 1s bent or curved toward and merges into the side wall of the male member near the shoulder of portion 3 thereof and forms the lower lateral end of a passage 8 which communicates through a short laterally projecting stub 6 with a suitable pipe connection attached thereto. At the upper end of the head, it is provided with an orifice 7 of sufficient dimensions that communicates with stub 71 of the female member and thereby forms a continuous passage for the flow of a liquid, gas or vapor through the stub 6 and through said orifice 7 and through stub b, or vice-versa. The other passage 9 extending through the male member is on the other side of web 5, and it is continuous from its lower end, which terminates in the axial stub 16 of said member, and its upper end terminates in an orifice 10 in the side of the upper end of the head in a plane below orifice 7 therein. Orifice 10 communicates with orifice cl of the socket and is elongated horizontally and is of the same dimensions as said orifice. The female member of my improved joint is stationary, and, if desired, may have suitable lugs 12 projecting therefrom to permit it to be attached to a suitable support. The male member of said joint is movable within specific limits from a center coinciding with the center from which the curvature of the spheroidal head is struck, but it is primarily the intention to keep the orifice 7 open to the bore of stub b, and the orifices 10 and cl always open to one another no matter what the relative positions of the male and female members are to one another, and keep both passages open all the time. It is not, however, beyond the range of the scope of my invention to make slight changes in the location of the orifices and he stubs, and by proper manipulation of the male member to enable the passage 8 of the joint to communicate with stub c and passage 9 to communicate with stub b of the female member.

The female and male members of the oint are retained in engagement by means of a packing ring or gasket 13, which is seated in the annular rabbet resulting from bulging the circular lower edge 14 of the socket outward and is held in position by means of the annulus 15, secured by screws to said edge 14:, as shown in Fig. 1 of the drawings, or by a gland-nut 16, as shown in Fig. 2 of said drawings.

I do not desire to be confined to the exact construction of the parts of my improved joint, as shown and described in this application, as it is evident it can, and in fact must be modified more or less in construction to adapt it for the many uses to which it can be applied. All such modifications I consider as coming within the scope of my invention. In Figs. 3 and L of the drawings, for example, I show one modified construction of my invention which consists in making the male member of the ball-joint so that the stub 6 thereof will project laterally therefrom in such direction that its axis will be at substantially a right angle to the axis of stub c of the female member instead of being parallel thereto as shown in the first two figures of the drawings. The only material change it is necessary to make in order to accomphsh this result is to twist the top portion of the dividing web 5 of said male member, substantially as shown.

Vhat I claim as new is:

A ball oint for pipes comprising a female member having a socket from which several pipe stubs extend, and a male member terminating in a spheroidal head fitting within said socket, said male member provided with stubs and with several separate passages that communicate with the respective bores of the first named bores, one stub of the female member being disposed in substantially axial alinement with one stub of the male member, and the stubs of the female member being at right angles to each other and each of said stubs being at right angles to a stub of the male member.

In witness whereof I have hereunto set my hand this 10th day of October, 1912.
